The nonlinear-optimization package

This library implements numerical algorithms to optimize
nonlinear functions. Optimization means that we try to find
a minimum of the function. Currently all algorithms
guarantee only that local minima will be found, not global
ones.

Almost any continuosly differentiable function f : R^n -> R
may be optimized by this library. Any further restrictions
are listed in the modules that need them.

We use the vector package to represent vectors and
matrices, although it would be possible to use something like
hmatrix easily.
